The gravitas of the big tree in the bush lingers in the minds of observers equipped and inclined that way, while all scan what else and possibly who else is nearby.
Many tree species make it to their peak size on riverbanks, including the jackal-berry and the sycamore fig. Riverine forest trees even push their neighbours to continually more elevated, shared canopies, as a place in the sun is a totally different life matter here than keeping up with the Joneses.
Bush counterparts only a little further away from the water can only shake a leaf in envy or wonderment at the achievements of their species mates with roots accessing moisture continuously. Those around them are, fortunately for them, hampered by the same problem, causing living standards, i.e. height to drop.
Because all that drink, including the big pushers and movers in large herds that fear little, frequent the river, underbrush loses out from trampling, hence the open patches in the shade.
Many careful ones arrive solitary when thirsty, keeping to these open areas where visibility is good. They contribute to the openness by nibbling away the new leaves sprouting, while contemplating all spots masked by obstruction and contour. Threats to the edible lurk in the prettiest places in nature.
